Description

Intelligent key cabinet based on mechanical lock Technical Field The utility model relates to the technical field of key cabinets, in particular to an intelligent key cabinet based on a mechanical lock. Background The key is mainly detected in place and misplaced and held by the RFID technology, and the key cabinet is mainly provided with RFID key boards with built-in electronic chips for each key, and the chips store unique identity information. When the key is put into the cabinet, the reader transmits radio frequency signals to activate the key plate chip, the chip feeds back information such as unique identification codes and the like to the reader, the reader confirms that the key is in place through analyzing the signals and synchronizes state information to a management system for record display, and when the key is taken out, the reader cannot read corresponding key plate signals, and the system automatically updates the key state to off-position. However, the intelligent key cabinet based on the RFID identification technology has the remarkable defects that because each key position of the key cabinet is required to be provided with an independent RFID reader, and the special mold is required to be developed due to the fact that the special structure is required to be matched with the RFID reader to realize limit and lock during key return, the shielding requirements on the cabinet body are very high due to multi-loop customization such as sheet metal processing, plastic mold design production, single chip microcomputer hardware design production and system software development, and the like, the whole cabinet is high in cost and selling price, and meanwhile, very strict requirements on the placement of articles such as incapability of contacting metal and the like are also provided, so that the application range of the intelligent key cabinet is limited. In addition, RFID key tablet is because of built-in coil and need match plastic structure, leads to the volume great, and it is inconvenient to carry, and can not make the mode of flexible terminal box, because the metal shell fragment can be used to flexible terminal box inside, can influence RFID reader and read. Disclosure of utility model The utility model provides a smart key cabinet based on a mechanical lock, which aims to solve the problems of high production cost, high selling price, limited application scene and large volume of an RFID key board in the prior art.
